Installation on Azure cloud

FreeSBC Azure Image

A virtual machine image is a single file that contains a virtual disk that has a bootable operating system installed on it. Images are used to create virtual machine instances within the cloud.

In the following sections, we will explain how to upload the latest FreeSBC image into your Microsoft Azure account and launch a virtual machine instance running the FreeSBC software.

Get a storage account

Follow next instructions in order to obtain a blob container in your Azure storage account. This blob container is required to upload and store a FreeSBC VM image. You can either use an existing storage account or create a new one but make sure that the storage account location matchs where you plan to create and run your VM.

Create resource group

If you need to create a storage account to upload VM image then you will need a resource group matching the location where you plan to create and run your VM. Here is a procedure to create a resource group if required to do so:

  • Log in to the dashboard.
  • Select 'Resource groups' item from the left menu.
  • From 'Resource groups' top menu, click 'Add' item.
  • The 'Create a resource group' dialog box appears.
  • Provide a name to this resource group.
  • Select the appropriate resource group location (where you'll be creating the VM).
  • Click the 'Review + Create' button.

  • Log in to the dashboard.
  • Select the 'Storage accounts' item from the left menu.
  • Select the appropriate 'storage account' then 'Blobs' container.

Accessing the FreeSBC

FreeSBC SSH Access

There is no root password by default, you will need to SSH onto the FreeSBC using SSH private key matching the public provided in the SSH public key when #Instantiate a FreeSBC instance. Login using centos as username.

For example, if your FreeSBC management IP is 192.168.178.30: 

 > ssh centos@192.168.178.30
   ECDSA key fingerprint is 5d:94:a1:93:0f:a4:7a:5d:41:cc:29:49:79:5a:58:f3.
   Are you sure you want to continue connecting (yes/no)? yes
   Warning: Permanently added '192.168.178.30' (ECDSA) to the list of known hosts.
   
   CentOS-7-x86_64-Minimal-1511/112/190195:197392, Fri  7 Apr 17:41:46 EDT 2017
   [centos@freesbc ~]$

Accessing the FreeSBC web portal

  • Open a web browser to the management IP of the FreeSBC, on port 12358. Example if your server address is 192.168.178.30, the URL would be:
    http://192.168.178.30:12358
  • You should get to the FreeSBC Configuration Wizard
